The display of each thumbnail with an appropriate paper size enables the operator to readily grasp the number of pixels constituting each image data corresponding to the thumbnail. Such display enhances the workability for selection of desired image data. Multiple thumbnails provided for respective image data are displayed as a list in a specific thumbnail display area on a window. The appropriate paper size of each thumbnail is shown on the upper right corner of the thumbnail. The appropriate paper size of each thumbnail is determined to be suitable for the print size for printing the image data corresponding to the thumbnail. The appropriate paper size is the paper size of the greatest dimensions among multiple paper size options stored in a paper size table that are sufficient for printing the image data having a specified number of pixels.
